High-Capacity 12V Super Capacitor Bank
The XS Power SB1260-27, a 12V super capacitor bank, stands out with its remarkable 1260 Farad capacity, making it a versatile energy storage solution compatible with Group 27 battery slots for various applications. With the capability to handle a maximum power output of 8,000W, it excels in high-demand scenarios, such as car audio systems, thanks to its quick energy discharge feature. Furthermore, by augmenting the vehicle's electrical system, the SB1260-27 significantly enhances power distribution, resulting in reduced voltage fluctuations and overall system performance improvement.
Frequently Asked Questions (FAQ)
- • Why did my voltage fall during deep bass even with a strong electrical system?
One SB1260-27 owner was running four Sundown X12 subwoofers, a Soundigital 12K amplifier, a 270A alternator, and a 55Ah lithium battery, yet still saw voltage issues during deep bass. After adding the SuperBANK, the owner reported seeing no lower than about 13.5V during heavy low-frequency music.
- • Does the SB1260-27 actually recharge quickly after a power burst?
SuperBANKs are designed to release energy rapidly and then recharge from the vehicle's electrical system. XS Power describes the technology as delivering power on demand and recovering quickly, making it particularly useful for repeated short-duration current demands.
- • Why can my amplifier still cause voltage movement after installing a 1260F bank?
The SB1260-27 improves transient support, but it does not replace the alternator or main battery. Its specifications show 32Wh of stored energy, meaning sustained high-power operation still depends on the vehicle's charging system and battery.
- • Could the Group 27 case be the wrong physical size for my vehicle?
Although the SB1260-27 is designed around a Group 27 footprint, it measures approximately 12.09 × 6.65 × 8.31 inches. Checking the actual tray, hold-down, terminal clearance, and cable routing is important because “Group 27” alone does not guarantee a perfect installation.
- • Why do my existing battery cables not line up with the SuperBANK terminals?
The SB1260-27 uses M6 terminal hardware, so factory cables designed around conventional battery posts may require an adapter or a different connection arrangement. A proper mechanical connection is especially important because this SuperBANK can handle extremely high current.
- • Can the SB1260-27 work alongside my lithium battery instead of replacing it?
Yes. XS Power states that its SuperBANKs can operate in parallel with an existing lead-acid or lithium battery. This makes the SB1260-27 a supplemental high-current device rather than a mandatory replacement for the vehicle's primary battery.
- • Why should I verify my alternator voltage before connecting this bank?
The charging voltage needs to remain within the SuperBANK's specified range. JEGS lists the SB1260-27 operating range as 12.0–14.25V and notes that 12V models charged from an alternator or stator should be maintained between 13.8 and 14.0V.
- • Is 31,000 amps a sign that the SB1260-27 can run my system continuously?
No. The 31,000A figure represents maximum current capability, not continuous energy storage. The SB1260-27 stores 32Wh, so its major advantage is delivering very large current bursts quickly rather than supplying a high-power system indefinitely.
- • Could the 19-pound SuperBANK create a mounting problem in a custom build?
Its 19-pound weight is relatively light for its electrical capability, but the unit still needs a secure mounting solution. Movement from vibration or hard driving can place unnecessary stress on M6 terminals and high-current cables, so the Group 27 housing should be firmly restrained.
- • Why might a high-powered audio system benefit from the SB1260-27 even when the alternator is already upgraded?
The real-world owner mentioned above already had a 270A alternator and lithium battery but still considered the SB1260-27 essential for their 12K audio system. Their reported improvement shows why an upgraded alternator alone may not completely eliminate short voltage dips caused by aggressive bass transients.
